By "worst" I am assuming per-capita figures. Obviously the US has a larger population than Spain and Italy, so comparing the raw number of cases isn't a fair comparison. On a per capita basis, we're not quite up there with some of Europe yet, but we will be.

But most of the US didn't really get their act together with testing until this week. We're a little delayed both in transmission and in testing, and the US is not showing any deviance from exponential growth at the moment.
